So I've been using Retrospect for a while now, and it works absolutely great on all but one server.

This server, of course...is the most important server we're using, Exchange! The backup will run fine, then just lose it's target networked destination. When I navigate back to the normal destination folder (Networked NAS) it then takes over 22 hours to back up. We only have about 120 clients using the Exchange server with caps on every e-mail account to keep the total size down. Other servers take about 10-30 minutes, this is an appending backup.

If so, the DAG is backed up using the passive db copy on most backup platforms. I have never used this particular product though.

I have seen issues with Backup Exec on networked locations though. If it loses connection to the networked resource, it goes into a ohcrappola state. Check to make that disconnect time longer, or map that particular resource with a persistent connection, and that might clear up the problem. It does sound like the disconnect timer which I beleive is default at 15 minutes or something like that, is changed to ahigher value in the registry. Might fix your problem. One other option is to attach a USB drive to the backup server, and see if the backup works good locally. Then you will know it is a timeout issue. Also, try running a continuous ping to the network resource the same time youa re backing up, and have it output to a text file. Then check the file and see if packets are dropping.

We have a backup script running for each server (12 Servers in total), many of which are only backing up specific folders. The Exchange backup is the only one that loses it's connection. They all point to the same NAS, and all get re-created about every 6 months or so when the old data is migrated elsewhere.

The disconnect problem is liveable, all I have to do is re-point it. It's the actual amount of time that it takes that is unbearable. For instance, it starts at midnight, and is still running right now, which means it's probably slowing down our Exchange services.

I am going to attempt a USB connection from the NAS to the exchange server, while undesired...I'd rather try that route then be running backups literally all day.
